Nettet6. aug. 2024 · The learning rate can be decayed to a small value close to zero. Alternately, the learning rate can be decayed over a fixed number of training epochs, then kept constant at a small value for the remaining training epochs to facilitate more time fine-tuning. In practice, it is common to decay the learning rate linearly until iteration [tau]. NettetLearning rate decay / scheduling. You can use a learning rate schedule to modulate how the learning rate of your optimizer changes over time: lr_schedule = keras. optimizers. schedules.

At extremes, a learning rate that is too large will result in weight updates that will be too large and the performance of the model will oscillate over training epochs.
